The Presa Canario comes from the Canary Islands, mainly Tenerife and Gran Canaria, where farmers used it to guard property and to catch and hold cattle. The name roughly means Canarian catch dog. Presas are massive, muscular mastiffs with a broad, square head and a short, coarse coat in fawn, brindle or black. Most weigh 85 to 130 pounds, and the coat sheds moderately but needs little grooming.
Many Presas are steady and devoted with their family, but the guarding instinct is strong, suspicion of strangers is typical, and some dogs don't accept other dogs, particularly of the same sex. In Austin that means a fenced yard, leash manners that hold up on a busy trail, and a handler who understands powerful dogs. Dogs vary, so watch how each one behaves.
